	Wave Models (Stormsurf)
		Input for the wave model is obtained from an atmospheric model.
		The wave models take the confirmed wind data from the analysis image of the atmospheric model and use it to estimate the winds effect on open ocean waters, projecting seas heights, headings, and in some cases, swell propagation.
		The seas depiction of the wave model typically will indicate the swell vector in that area as heading southerly, influenced by the prevailing local winds and resulting short period wind waves, not north (the heading of the underlying long period swell).

	Quantum chemistry - Wikipedia, the free encyclopedia
		The foundation of quantum chemistry is the wave model of the atom as a small dense positively charged nucleus surrounded by electrons.
		However, unlike the earlier Bohr model of the atom, the wave model describes electrons as "clouds" moving in orbitals, and their position is represented by a probability distribution, rather than discrete points.
		This was the first attempt to describe many-electron systems on the basis of the electronic density instead of the wave function, although the Thomas-Fermi model was not very successful in the treatment of molecules.

	Wave Theory for Glider Pilots
		The shape of the wave may be controlled by other factors and, as is illustrated later, the horizontal wind speed is itself modified by the shape of the wave.
		Wave flow was set off by a redge whose shape was defined by a convenient mathematical formula which produces a bell shaped obstruction to the horizontal airflow.
		The waves are not symmetrical, they tilt forward at a marked angle to the vertical and in certain sections the streamlines are practically vertical ahead of the wave crest but have only a gentle slope on the downstream side.

	The Wave Model for Capping and Particle Movement on Cells
		The wave model now to be described is likewise unproven but the grounds for affirming it are exactly those with which Darwin justified his belief in evolution.
		Waves on such organisms are an evolutionary adaptation reflecting the survival advantages of an ability to move.
		The "waves" are deformations of the membrane due to an underlying organelle, for example a mitochondrion, moving inside the reticulopod and in contact with a deep-lying microtubular bundle, a type of cytoskeletal structure not based on actin or myosin.

	Cell capping and the refusal to explain
		The wave model is also incomplete; it too lacks this most important part, the response of those to whom it was addressed, but the reasons are different.
		Ignoring the wave model is the same as rejecting it but he seems reluctant to accept ownership of his action, let alone its implications and consequences.
		By contrast, the wave model, which is almost certainly correct, is little cited and therefore appraised as being of low quality, with all the expected sequelae arising from decisions in scientific management.

	Hybrid Wave Model and Its Applications
		The HWM divides a wave spectrum into several wave bands and employs the MCM to formulate the wave-wave interactions of close frequency wave components and the PMM to formulate interactions of wave components that are relatively far apart in the frequency domain.
		It is concluded that the surface intermittency effects and wave nonlinearity are both important under relatively strong nonlinear waves when linear wave theory and modified linear theory may considerably underestimate the wave forces.
		The sensitivity of wave forces to the cuttoff frequency, that was found by Hu et al, (1995), is caused by the divergence of the MCM for broad-band and relatively steep spectra.

	Wave Model
		However, in UK coastal waters a more accurate model is needed, and to provide this a new UK waters wave model has been developed, which covers the European continental shelf from 12° W, between 48° N and 63° N, at a resolution of 1/9° longitude by 1/6° latitude.
		Model data from the global and regional wave models are available to the wider oceanographic community via the internet using our Data and Products Distribution Service (DPDS).
		Wave model data and products are available 'free of charge' to the research and education community for non-commercial use; for commercial use a small charge for the information will be made.

	MWFM - The Two-Dimensional Hydrostatic WKB Gravity Wave Model (Site not responding. Last check: 2007-10-29)
		MWFM - The Two-Dimensional Hydrostatic WKB Gravity Wave Model
		The NRL Mountain Wave Forecast Model uses two-dimensional hydrostatic WKB (linear) gravity wave equations to represent the radiation of the mountain wave into the upper atmosphere due to low-level flow across the ridge.
		Our experience is that these simplifications lead to the model being "overactive," in the sense that, when the approximations fail, it tends to overestimate levels of mountain wave activity.

	The Particle: Standing wave atom model
		The whole atom is a standing wave in three dimensions, and all known effects have to be described by electromagnetic standing wave geometry.
		Unlike the conventional model, where the space between electron shells is described as a void and empty space, in our model it is the space in between the inscribed and circumscribed spheres, which contain the inward and outward going spherical waves forming up the 3D standing wave shape.
		The Moon model is thus consistent with much of the same experimental data which underlies the periodic table of the elements, and explains additional features not explained by the modern, electron-configuration presentation of the periodic table.

	Harbor Wave Model Goes International

	WL :: Boussinesq-type wave model
		In coastal areas, wave dissipation and non-linear wave-wave interaction are dominant processes.In order to obtain a correct prediction of both the total wave energy and its distribution over the wave spectrum at locations in the coastal region, numerical wave prediction models should include an adequate description of wave propagation, non-linear wave-wave interaction, and wave breaking.
		Wave breaking is modelled in TRITON through the use of an eddy viscosity model, which guarantees energy dissipation.
		The breaker model has been validated for long- and short-crested waves, either regular or irregular, using different values for the wave steepness and wave height, and even different water depths and angles of incidence.

	Energy Citations Database (ECD) - Energy and Energy-Related Bibliographic Citations
		Asymptotic forms of the wave model are considered and analytical solutions of typical linear stationary and nonstationary problems of chemical reactor engineering interest are obtained and compared to those for the Fickian dispersion model.
		The wave model leads to efficient analytical solutions for linear problems, which in principle differ from the solutions of the Fickian dispersion model; only for slowly varying concentration fields do the solutions of both models approach each other.
		Old experiments that could not be explained with the standard dispersion model are reconsidered and explained: the change with time of the variance of a concentration pulse when the flow direction is reversed and the difference in values of the apparent axial dispersion coefficient and the back-mixing coefficient in a rotating disk contactor.

	Introduction
		Here, the wave forecast is validated against the wave analysis, and the period is August 1995 until January 2001.
		Ultimately, it is expected to have a model consisting of the atmosphere and the oceans where the ocean waves are the agent that transfer energy and momentum oss the interface in accordance with the energy balance equation.
		Ocean waves are in general not in an equilibrium state determined by a balance of the three source functions, because advection and unsteadiness are important as well.

	Alfvén Wave Model of Auroral Dynamics (Site not responding. Last check: 2007-10-29)
		In this case, the resulting auroral dynamics depends upon the non-uniform nature of the plasma medium through which the waves propagate, particularly in the direction perpendicular to the magnetotail current sheet.
		Plasma is accelerated across the wave fronts, and an outflow region of reconnected plasma is thus formed.
		The model predicts that arcs in the southernmost part of the auroral oval will have a poleward motion, while arcs in the northern part, mapping to larger downtail distances, will display both poleward and equatorward motion.

	Wave
		The WAVE model (Water and Agrochemicals in the soil, crop and Vadose Environment) describes the transport and transformations of matter and energy in the soil, crop and vadose environment.
		It's a deterministic, numerical and integrated model that simulates the behavior of water, heat and agrochemicals in the vertical direction.
		The WAVE model is an integration of earlier models such as SWATRER (water module), SOILN (nitrogen module), LEACHN (heat and solute modules) and SUCROS (crop growth module).

		For the accurate and efficient modelling of the dynamics of surface waves in shallow coastal regions and harbours the Boussinesq-type model TRITON was developed at WL
		The wave model is capable of computing wave conditions in regions where complex phenomena occur within relatively short distances (e.g., severe wave breaking, wave reflection, wave refraction, wave diffraction, directional spreading, etc.).
		Wave breaking is modelled by an energy-dissipating, yet momentum-conserving eddy-viscosity model (see Figure 1 for a snapshot of breaking waves over a submerged shoal).

	WWA - World Wave Atlas - Wave and Wind Atlases for any country worldwide
		Time series of wave heights, period and direction; primarily these are deep water data, but shallow water time series can also be provided if the customer does not have an in-house wave model to perform the transformation.
		An offer for wave data for a particular location or an atlas for a given area, country or region will be given if you send us an e-mail specifying the area or location of interest.
		In this case, the satellite data from WWA allows you to assess the spatial variability of the wave and wind climate over a larger area around the main site of interest, in addition to giving greater flexibility in producing different statistics, which maybe were forgotten, or which you were unaware of the need for, initially.

		Because the present Gulf of Mexico model is a second generation model and does not consider waves propagating into the gulf from the Atlantic Ocean or the Caribbean Sea (It assumes the gulf is a closed basin.), it cannot predict realistic hurricane wave conditions in the gulf.
